ALEXANDER WINToN, or CLEVELAND, omo, AssIoNon To wn'rroN G'Asnremnsnnl -MANUFACTUBING COMPANY, F CLEVELAND.,OH IO Specification of Letters Patent. Application :nea september 11, 1912. serial No. 719,34.

To all whom it may concern Be it known that I, UEx-morn IVINTON, a citizen ofv the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented .c"erta1n new and useful. Improvements in Self-Starters, of which the following is a specification, reference being had' therein to the accompanying drawing.

' This inve tion relates to improvements in selflstart'ers, for explosionengines, and is particularly intended for use in connection with stationary and marine engines.

The type of self-starter involved herein, is that in which there is a supply of compressed air in a tank, which is in communi- `eatioriw'ith a distributing valve geared to the. engine to rot-ate in unison with the engine 'crank-shaft to permit the compressed air` to pass tc the cylinders in the order. in which they are fired, and when they are on the explosion stroke.

The object of the present improvement 1s to provide means for locking and unlocking the check valves past which the compressed air flows, whereby the valves can be locked tightly to their seat after the engine is in operation to prevent any leakage thereby, and the noise consequent to the operation of such valves. when openingA and closing under the action of the engine pistons.

In the accompanying drawings-Figure 1 is a side elevation of a portion of a multiple cylinder engine showing my improvement applied thereto. Fig. .2 is a side elevation of a multiple cylinder engine with my'improvement applied thereto.

Referring now to the drawings, 1 indicates the cylinders and 2 a distributing valve case, which is in communication with the tubes 3. These tubes 3 are in communication with the cylinders 1 through a valve passageway 4. These passageways are controlled by check valves 5, the .stems 6 of which pass loosely through the valve casing 7 The outer-ends of the valve asings 7 are externally screw-threaded at 8. which re ceive internally screw-threaded hand wheels 9. VVith'the valves and hand wheels in the positions shown in Fig. 1 the valves 5 will be opened by the suction of the pistons (not shown) within the cylinders and are closed by the compression movement of the pistons. This is the position and action of the `valves when the engine is being started. [Af-ter the 4engine picks up its own explosions-and is running, the hand wheels 9 'areturned out- "wardon the' screw-threaded extension of the valve casings 7 and engage the vadjustable nut washers on' the valve stems' and ltightly close the valves. This .enables the valves to be tightly closed to prevent'- any 'escape thereby yfrom the engine cylinder, and pre'- vents it from working back and forth, mdk# ing an undesirable tapping noise; y The vtype of self-starter'here shown is well known in the trade, and to those-skilled in the art, and need lnot be elaborately del scribed or illustrated. @Forthe purposes of this case it is deemed ,suilicient to generally vdescribe .and generally show the type of.

starter. In this type. of .Starter asuitable pressure storage tank 11 is provided, and

this'tank may be stored with afluidpressure in anyl desirable manner (not shown) through the inlet 12. The ta'nk has-,an out let 13 which communicates .with a casing-(14.' This casing has a screw-valve 15- to closthe said passageway and a reciprocatingl valve 16, which may be opened by the foot of the operator. A pipe 17 establishes communr cat-ion between the casing 14 and the timing' valve easing As previously stated, this valve-casing has a separate communication 3 with each of the .engine cylinders, and these pipes 3 communicate with separate passages 3' within the said casing, and the valve 18 is provided with a passage-way 19 adapted to register successively with the passage-ways 3 and to thereby admit the pressure from the tank 11 to the engine cyl- Patented 13, 1911.4..

inders in proper sequence to cause the engine to rotate.

To start the engine the valvesand hand wheels are put in the position shown in Fig. l; the valve 15 is open. A pressure on the valve 16 will then establish communication between the tank and the casing 2, the pressure passing through the opening 19 of the valve into the registering passage-way 3', causing the pressure to pass into the cylinder in communication with that particular passage, causing the engine to move and the valve 18 to correspondingly rotate, until the opening 19 of the valve Ahas first cut oit com` munication with the passage-way 3 and is in communication with the succeeding passage-way 3 to carry the pressure to the next cylinder in the sequence of the normal operation of the engine? As'soon as the engine ,has-picked u I: its normal operation: the valve 16-is release and thereby closed.

'l `4The object of the screw valvel'isto 'pela` mit the communication between-.the tank 11 and the valve 16 to befgtigh'tlyclosedywhen the motor is left for any1 considerable length o f time and thus prevent 'The loss of pressurewhichniight occur past therecipro;

'Check '25 valve within said supply "and outwardly closing in respect to the cylinder, and means for locking said valve in its closed position, for the purpose described.
